Chances are yours will count less than a select few. Each state's Electoral College votes are based on the size of its congressional delegation, not its population. Because of that, a presidential vote in Wyoming mathematically counts more than three times as much as a vote in Ohio, at least in terms of choosing electors. (AP Photo/Steve Helber, File)
